GAS-HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 443,829, dated December 30, 1890. Application iiled December 5, 1889. Serial No. 332,654- (Model.)

To a/ZZ whom it may concern:

Be it known that I, SILAs B. I'IAvnNs, ot Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Gas-Heating Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to that class of heaters for warming rooms, &c., in which gas is used for fuel; and its object is to produce an apparatus of that class that will be effective, ornamental, and light enough to be used in immediate connection with the arm of a chandelier or a gas side bracket by being placed over or around the burner in its usual position.

It is fully illust-rated in the accompanying drical shape, (see Fig. 1,) and the upper partA is composed of a series of conical rings b, attached to vertical strips of material extending up from the luted portion of the heater These conical rings are placed one above another, so as to leave an annular openingbetween the iiaringlower edge of one ring and the-contracted upper edge of the ring next below it.

The bottom of the heater may be left open or made partially closed, according to the area of the annular spaces left between the rings above, that the space for admission of air may be properly proportioned to the space' provided for its exit after being expanded by heating in passing through the chamber. The top consists of a cover c, made with an edge slightly turned down to keep it in place, and left loose, so that it can be turned around or taken off, if desired. Aflat circular plate d, made rather smaller than the head of the heater, has a rod or wire` a attached to its center, by which it is suspended from the top of the heater in the center, and may be held in a horizontal position, as shown, or inclined by bending the wire a slightly so as to take the position shown by the dotted lines in Fig. 2. This plate CZ serves the purpose of a guard or deiiector to turn the current of heated 4air out through the annular openings in the sides of the heater and keep it'from coming in contact with the top- It may be set at an angle, as shown in the dotted lines e e, Fig. 2, so as to throw the current of heated air toward the outlets on any side oi' the heater to the exclusion of the other side by-turning the top of the chamber to which it is attached'around, as above stated, which in some cases is necessary, as when the apparatus is used on a gas-bracket at the side of a room or near a mirror where the hot air, it allowed to pass out that side might injure the appearance of the walls or the frame of the mirror. The deliector d, after being set at an angle, as in Fig. 2, can be brought to face any side of the heater by turning the top to which it is attached around in its place.

The apparatus is supported on a wire framework g, that has a ring in its center toV pass over the socket of the burner, and may be held in place by screwing the burner down on the ring.

The operation will be easily understood by referring to the drawings. B is the arm of a chandelier or bracket. The burner fis Yunscrewed, and the ring in the center of the wire frame-work g is placed on the screwsocket where the burner was, and the burner replaced and screwed down firmly into the ring in the frame. The heater A is then placed on the frame g and the gas turned on at the cock j and lighted. A draft of air is produced by the heat of the burner, which passes in through the bottom in the direction of the arrows o o and thence up out through the annular openings between the rings in the direction of the arrows s s, being heated to a high degree in passing through the IOO heater both bythe gas-flame and the metallic sides of the heater and delleetor.

The shape of the body of the heater can be largely varied to make it ornamental and 5 suit the taste of the user Without depart-ing1 from the principle of the invention.

One great advantage of this heater is that it can be used Where there is not sufficient floor-space available for a heater of any of 1o the usual kinds and its perfect seenritywith regard to children, as it is ont of the Way of every one and delivers its heat from above downward. l

Having thus described iny improvement,
